为考察聚能网尿素、含腐殖酸尿素、含腐殖酸磷尿素等新型增效尿素对棉花生长发育及产量构成要素的影响,开展了田间小区试验。结果表明:在施肥量保持一致的条件下,追施新型增效尿素对棉花的生长发育及产量有促进作用;追施含腐殖酸磷尿素的棉花,其株高、茎粗、叶绿素相对含量等生长指标和果枝数、铃数、产量及产量构成要素等优于其他处理的,其中棉花产量较追施含腐殖酸尿素、聚能网尿素、普通尿素的分别提高4.9%、12.1%、13.9%。
In order to investigate the effect of new type synergistic urea such as Ju-Neng-Wang urea, urea containing humic acid, and phosphorous urea containing humic acid on the growth and yield components of cotton, a field experiment is carried out. The results show that under the condition of same amount of fertilizer, topdressing of new type synergistic urea has a promoting effect on the growth and yield of cotton; the growth indicators such as plant height, stem diameter, relative chlorophyll content and the number of fruit branches, bolls, yield and yield components of cotton topdressed with phosphorous urea containing humic acid are better than that of other treatments. Among them, cotton yield increased by 4.9%, 12.1%, and 13.9%, respectively, compared with that of treatments topdressed with urea containing humic acid, Ju-Neng-Wang urea, and common urea.
